Say what you say, but I love The Couple in the Cave.
I just love Brennan in it, the way she cockblocks Booth and Barbie when they kiss, how obviously jealous she is, her laugh when Cam points out she’s jealous and that’s why she’s acting that way, Booth telling Brennan they acted out of love while saving each other and that she knows that (they both look so gorgeous in that scene), and of course, the heartcrushing ending with Brennan drinking alone while Booth leaves with Barbie.
Also, Clark’s classic butt naked quote.
